Re: Mitsubishi HD1080 Power Problem


The diagnostic is a two digit response so you must be getting a 2-2 which indicates a short detect. One of the secondary supplies is going low, likely the -24v line. Check the pico fuses. You probably have a bad convergence output IC but there are other areas that can cause this, The convergence outputs are STK392-110. Replace them with the STK394-160e from the hitachi kit X480295 available from TriTronics if that turns out to be your problem.
